NASA and ISRO Launch Groundbreaking Earth-Imaging Satellite, NISAR
The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite was successfully launched on July 30, 2025, marking a significant achievement in international space collaboration. The $1.5 billion Earth observation satellite was launched at 5:40 pm IST from the Satish Dhawan Space Centre in Sriharikota, aboard India’s GSLV-F16 rocket.
NISAR is the world’s most expensive Earth-imaging satellite and the first to use dual-frequency radar systems. The 2,392 kg spacecraft is equipped with both L-band radar (provided by NASA) and S-band radar (developed by ISRO). This advanced technology enables unprecedented monitoring of Earth’s land, ice, and ocean surfaces with a resolution of 5-10 meters.
The satellite will orbit Earth 14 times daily, capturing comprehensive surface data every 12 days. This data will be instrumental in predicting natural disasters, monitoring climate change, tracking agricultural patterns, and providing early warnings for earthquakes, tsunamis, and volcanic eruptions. “This is India’s scientific handshake with the world,” said Science Minister Jitendra Singh, emphasizing the mission’s role in enhancing global disaster preparedness and environmental monitoring.
